Confirmed on Pocket Now - 0 to 100% in 7 hours.
Appalling

The ubergizmo.com review says 3 hours.

I for one don't trust the 7 hour figure.
Wait for a few more reviewers to test it.

It's very possible that he used a low volt phone charger or.....charged it through the computer. The Kindle Fire is around 2:49 I think, the battery is very slightly smaller on the Nexus 7 so it should charge a little faster.

and don forget they don't have the n7 that we will have, maybe charging time is less on the consumer models

I use the HP Touchpad charger & it takes around 2-3hr or less.

one thing i dislike about note10.1

the charging time. this thing takes a really loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong time to charge (about 5+hours). i know it's 7000mah, but my xoom (6X00mah) takes only about 3 hours , and both of them have almost same battery life (note is slightly better)
as i know xoom uses 12V to charge, how about note?
Mine charges up to about 98% in about 3 hours from about 30%
Im on the original firmware on the 8013 white version. Last night i went from 3%- 79% in a little over 2 hours. I cant complain about that. Also, i turn it off when i do that. When i charge it while on, i put it in power saver mode, and it charges well enough for me. I think the first time it charged it took about 5 hours...but since then, very good.

Very usefull information. The WHITE version. I wonder the grey or black version how much it takes to charge. I think black version charges more quickly because black absorbs energy, and white doesn't, what do you think?

And since you have no Samsung devices in your signature I'm assuming you just came here to share that observation? Too much time on your hands?
Mine def is a slow charge, but honestly never timed it. could be 3 hrs, but feels like 5+ or is it. not sure . i think.

Is this using the power outlet charger? Or is this using a 3rd party charger? I don't have any problems charging my Note 10.1. Takes about 45 minutes or so to charge from 80% to 100%

I alternate between Note 10.1 and Nexus 7 while the other one is charging. Regardless, charging time hasn't been an issue and am happy with it. Note 10.1 gets about 8 hrs of on screen time versus about 6 hrs on Nexus 7.
My first Note 10.1 (White 16gb) took awhile to charge, it was much longer then expected. I even posted a similar question here and had the same responses, minus the idiot. I exchanged it for a 32gb version and the second one charges much more quickly, leaving me to believe the first Note I had was faulty.

You need to make sure your charger has an output of 2A. Anything less will take way longer.

Mine (white, 16Gb) charges much much slower than my Xoom. The Xoom will go from 0 to 70 in just over an hour.
I just discovered the power saving mode and will test how that impacts charging. Right now I am using the Samsung charger connected to the Samsung dock and its slow. Hopefully not an issue with this tablet.

Great story bro...I wish I were that creative..
Btw everyone, there are no differences between the deep grey and the white other than aesthetics. And the only difference between the 16 and 32 gb models was how much you were willing to shell out for more storage space. I am just getting tired of people posting a paragraph describing their device before getting on with describing a problem...all you need is which version you have ie, 8000, 8013 etc. Flame me if you want, it is my opinion.
Now I step down from my soap box...night y'all.

Total Charge timing of nexus 7

Any one know how much time n7 will take to charge 100%.
- Using power adapter
- Using system USB port.
Review stated it takes 3.30 hrs for ac charging.

Yeah 4 hours here too. At least.
about 2-3 hours here
dont mind though as ive been out using heavy for whole days and still got back home at midnight with 65% left luv the nexus battery
Id love to hear how some claim to have fully charged their Nexus in 2 to 3 hours, it takes me 4 hours minimum to fully charge it from around 6%, i haven't let it drop beyond that yet.
I'm not 100% sure on the time but about 1-2 hours, but then again the lowest I've ever had it is 13%. I tend to keep it plugged in if I'm going to be doing something battery intensive like play games or a lot of web browsing, and tend to turn it off over night and pick up notifications on my phone as it doesn't give off as much light from the back light as my N7.
I love the battery life on the N7 as it could probably go for at least a day and a half on battery if I left it on all the time and used flight mode over night, but I don't want to kill the battery and have to mess around inside it to change the battery.

It depends on what ac adapter you use, and how much current it puts out. I originally used my incredible s charger and out took forever
With the Asus OEM one it takes around 3 hours from around 0-5%

This here. It is horses for courses.
As for the debate on charging times. 3-4 hours is the norm for most of us. Given different tolerances in both the charger and battery some migh be on the lower end of the scale and some higher.
Just remember to use the OEM Asus adapter as it puts out 2amp at 5v. (Or a 2a equivalent) .
Most phone chargers and USB ports on comps/Xbox etc only output 500ma (.5 amp). You can use them but it will take a good ten hours to charge with them.

[Q] Using Gnex charger with my Nex7 (and vice versa)

Hi,
I just bought a Nexus 7 and noticed that it has a different charger than the Android smartphones I have, e.g. Nexus S and Galaxy Nexus. However, the connection is still the same.
My question is, is it safe to use a smartphone charger with my Nexus 7, just to have less stuff lying around? Is it safe to use the 7's charger with my smartphone? Will I break my devices if I do it?
Thanks!
Perfectly safe. The Nexus charger puts out slightly more current than most phones, worst case it will charge them slightly faster, just as a phone charger will be a little shower with the tablet.

You won't break your devices, but it would take an extraordinarily long time to charge your N7 with the phone's charger. Conversely, the phone is not going to charge exponentially faster using the tab's charger. So, all in all, wile it's not ideal, you won't be hurting anything.

So I can just keep my Nexus 7 charger and use it for every other gadget, and put the other chargers into a drawer? That's nice to know, thanks guys.

The phone won't charge any faster using the N7 charger, but the tablet on the phone charger would be significantly slower- to the point that even moderate use while plugged in would result in still draining the battery. Assuming no use while charging, the tablet would require several hours more than normal for a full charge.

I disagree, my galaxy prevail charges twice as fast on my n7 charger than with a standard phone/car charger. However my n7 does take forever on the phone/car charger. Literally like 8hrs+ to reach 100%.

Check the 'mA' or 'A' rating on the charger.. The higher it is, the faster it will charge.
the charger I got bundled with Nexus 7 is outputing 2A (2000mA to be exact), which is quite higher than most phone chargers
(I've got chargers with standard 500mA & with 800mA).
I've been using the Nexus 7 charger for charging my ZTE Blade and nothing seems wrong using it..
A phone's charging circuit will automatically restrict the current to the specs needed by the phone.
PS: 'A' stands for 'Amperes' & 'mA' stands for 'milli Amperes ', both are units of measuring current.

Charging nexus 10 with galaxy note 2 charger

OK guys I got my nexus 10 last night and I finally killed the battery thru this morning .first time charging it and instead of using the stock charger I'm using the note 2 charger .in one hour its at 20 % and I haven't touch it and the tablet is on .I have nfc turned off and wifi is still on .I also had disabled Google currents and Google + (I don't use Google +) .Is this fast ?I don't know charge times with stock charger cuz I havent used it yet

Oh and another thing ,I don't use Google currents anymore either .its nice but I had on my old phones and THAT APP IS A BATTERY SUCKER FROM HELL !

OK some research ...
1.the charger is fine that comes with the nexus! It charges average. Roughly 6 -7 hours to a full charge
2. Note 2 charger is about the same with nexus charger with charging time. Maybe barely faster!
3. With original charger: I'm easily ,constently on my nexus playing videos, downloading, browsing,etc!its not hurting my charge and not decreasing any charge time. I wanna say its partial blame to a certain app called GOOGLE CURRENTS! Without disabling it, constantly runs background and killing battery. Have GPS on google maps constantly running background killing some juice.
4.nfc turned off as I wouldn't use it. I'm sure this is helping my battery
I did just get my nexus 32 gig on the second batch when they became available again on google play. Could there be a bad 1st batch considering the stuff I'm reading on complaints ,possibly. I can only compare my old galaxy tab 10.1 wifi 32 gig to my new nexus and both battery charge times about on par with each other. Galaxy tab edges out barely on time and lasting juice.
Take my observations for what it worth ...just my experience with this tab
Sent from my Nexus 10 using Tapatalk 2
I am just using my note 2 charger. Before I did I made sure the ratings were the same so I knew there were identical. I once tried charging my note 2 with an older charger and it was SLOW.
I've only charged the N10 once but my time from around 2% to fully charged was consistent with what had been reported as normal here.
So do the chargers for the Nexus 10 and the Galaxy Note II have the same ratings\amperage output? The reason I ask is that I have a UK Note II charger but a US Nexus 10 charger and here in Ireland the UK one works without having to go out and buy an extra adapter. I would ideally like to use the Note II charger to charge the Nexus 10 without having to go an pay for an adapter, I would rather spend the money on a nice case for the Nexus 10
Cheers,
M

Look at the Amp rating on note ii charger.
If it's 5v 2A, it's the same thing, and will charge nexus 10 equally. If it's less, it's slower.

Exynos variant does not support fast charging while Qualcomm does...
35 hours or more of total battery life with 6 1/2 to 7 hours of screen time. I play a lot of intense games so my screen time is lower, but I've easily been able to get 5 1/2 of screen time out of this thing playing Galaxy on Fire 2 and it's like one of the most demanding mobile games available.

I was using previous generation of 10.1 on almost minimum brightness, and was getting more than 10h of screen time. Yes, I've been using it indoors mostly, and my eyes weren't asking for more. I am getting new 10.1 in couple of days, and hope to have similar SoT...

the exnyos does have a full powered charge at up to 80% then trickles to 100%. it takes mine about 4-5 hours to go 0-100. it doesn't use qualcomms quick charge tech, but it doesn't trickle the whole way. if it takes 7 hrs then the charger or cable could be bad or the tablet may not be telling the charger to send 2amps.

It's pretty slow. Almost 30% slower than the N10.1-12 a lot of us came from. It's the move from Samsung's proprietary 30-pin connector to standard microUSB. The N10 using a pogo pin charger (vs. its standard microUSB) is about 30-40% faster than what's shown below.

that article was what concerned me before i bought the tablet, but i went ahead and got it anyway. the only time that mine had actually nearly taken that long was on the first few charges. sometimes it would be stuck at trickle and wouldn't pull the full power (i actually only get an average of 1.6A from the stock charger and cable - I've never verified the volts. i could stick it on my killawatt and see what it pulls. after those few quirks i don't see charge times as long as anand has reported. it's always that last 80% that's a killer. it seem to take from 1.5-2hrs depending. i can go from 37% to 80% in 2hrs then i have to wait nearly as long for the last 20%. i think it's a battery saving technique that samsung is using. toyota's reports showed that charging the battery to 80% capacity extened the life. on my 700t there's a battery saving option that won't charge the battery over 80%.

USB 3.0 doesn't impact charging time, at least not yet. And the S-800 version of the N10.1-14 does use the same SoC as the N3 and someone here with a SM-P605 reported getting a full charge in about 5 hours and 80% in 3.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.
The Note 3 does charge faster overall compared to the SGS4 however thanks in part to the new PMIC (PM8941) which is part of the overall 8974 platform story.

lol, that's actually a feature that Donald Trump insisted be included in all white and black Notes to remind people they aren't part of the exclusive 1% who actually have solid gold Notes. Interestingly the solid gold Note consistently shows 1%.
See this is the odd thing - I had this tablet a month ago but got it exchanged because I found a cheaper one anyways on that tablet I am positive I was getting 6hrs screen time which was some youtube videos but majority was browsing the internet and that was it.
However on this new one I just got 9hrs30mins and that was with watching a 2hr movie streaming online, about 2hrs worth of streaming tv shows, loads of web browsing and also a little bit of Youtube...Personally I think this is awesome screen time (Mind you it's my first tablet so nothing to compare to but still). I am very happy with charge (5hrs) and battery drain on this tablet - very nice indeed.
Would love to squeeze 11 hours out of this like someone had in the earlier posts but that seems a tad difficult considering I already have brightness pretty low and all pointless apps disabled.
